This Electronic Control Thermostat (thermistor included) replaces the mechanical thermostats in the 1994 Hot Spring Classic, Grandee, Highlife, Jetsetter, Prodigy, and Sovereign spa models. This retrofit remedy was introduced to solve the mechanical thermostats’ high failure rate in this model year Hot Spring. Due to the backflow of electricity from the relays, the mechanical thermostat’s contacts would quickly fuse together causing it to fail sometimes within a week of replacement. This upgrade cures that problem.
Technical Specs:
Copper Lead Length: N/A

I've been meaning to write to thank Craig for the help with my 1996 HS Sovereign. I was so thankful for his time and expertise! He helped me figure out that the circ pump was the culprit. The video on line was a big help too. Especially the wine corks to plug the tubes. I wish there were a Backyard Plus type service for every other part of my life.On 03/13/2023 by M. C.

I called backyard plus about a problem with my hot tub. Great help. He had me try a couple of tests and determined what the problem was. I ordered the part, and fixed it with no problem.On 03/13/2023 by G. H. (verified customer)
The staff at Backyard Plus was very helpful with getting me all the parts I need to replace one of the diverter valves and associated plumbing on my 20+ year old Hot Springs Grandee. The order was shipped very quickly and correctly. I have yet to make the repair, but I know I have everything I need to complete the task at hand. Prices were reasonable and shipping was free. I will definitely use Backyard Plus for any future parts I need for my pool and spa.On 03/10/2023 by D. K. (verified customer)
